ATI’s upcoming RS690 series of chipsets include the RS690, RS690C which are both integrated graphics products. There isn’t much mention of official product names for RS690 and RS690C yet, however, the roadmap hints towards Radeon Xpress 1250 and Radeon Xpress 1200 for RS690 and RS690C respectively. Both integrated graphics chipsets feature a Radeon X700 derived graphics core with support for AVIVO technology. AVIVO features such as vector adaptive de-interlacing and advanced downscaling are supported for an improved media PC experience. The graphics core is equipped with four pixel-pipelines as well.

There’s very little difference between the RS690 and RS690C, with the exception of native HDMI support. RS690 includes support for HDMI output while the RS690C removes it for lower costs. Derived from the RS690/RS690C is the upcoming RX690. RX690 is ATI’s single PCI-Express x16 slot solution for the enthusiast that doesn’t want support for ATI’s CrossFire multi-GPU technology. The RX690 chipset will be completely pin compatible with RS690. There’s no mention when RS690 or RX690 will be available, however RS690C availability is expected in November.

In a move to push the RD480 CrossFire Xpress 1600 down to a value level, ATI will release RD550for the less than $100 market. This will move RD480 CrossFire Xpress 1600 motherboards down to the $60 price point and leave RD580 CrossFire Xpress 3200 at the $120+ price point. ATI has named RD550 CrossFire Xpress 3100. RD550 is based off of ATI’s high-end RD580 CrossFire Xpress 3200 but lacks the dual full-speed PCI Express x16 configuration. ATI is aiming to take on NVIDIA’s nForce 570 SLI with RD550 CrossFire Xpress 3100.

Further down the product roadmap are the RD790, RX790, RS790 and RS740 chipsets. These chipsets will arrive in the second half of 2007 and first half of 2008. RD790 will be the first to arrive and will carry the CrossFire Xpress moniker. This will be a high end enthusiast chipset with support for AMD’s 4x4 platform. It will support socket 1207 processors, AMD’s Hyper Transport 3.0 specification and quad-core processors. Four graphics cards and PCI Express 2.0 will be supported as well. Replacing the upcoming RX690 will be the RX790. RX790 will be a single graphics slot product with support for Hyper Transport 3.0.

On the integrated graphics side of things will be RS790 and RS740. These two chipsets will feature an integrated graphics, though it is unknown which graphics core it will be derived from. RS790 will be the high end integrated graphics offering with support for Microsoft’s upcoming DirectX 10 architecture. ATI’s Universal Video Decoder is also supported. RS740 will have a DirectX 9 graphics core and no support for ATI’s UVD.
